Hello denise,
Well u have 1 way to do that, a query linked with logdb,
then a simple explain :
1 - if ()
2- a player wear thief suit and summon thief vehicle (hourse, camel or whatelse);
2 - is in region of (towns ..);
3 - Do a return -
/*-- Link this query with log db and use the operation of opening NPC or teleport .. (or even all operations) > the operation of logdb
4 - don't forgot while writing ur query to write the table name like that sharddbname.dbo.tablename (to make logdb connect to sharddb while executing the log)
u may also make the query execute before teleporting or casting a return scroll ..
At last , if(){return}; make a dc , then under return make a query which dismount the camel and delete all goods with it..
So the query will do : anyone will try to enter the town with camel while wearing a thief cap , DC and unsummon the camel and no goods ..
Sorry, i can't write such a query will take much time , hope i explained good
Good luck
